Inspection and Verification

 WARNING: KEEP BATTERIES (10655) OUT OF REACH OF CHILDREN. BATTERIES CONTAIN SULFURIC ACID. AVOID CONTACT WITH SKIN, EYES OR CLOTHING. SHIELD YOUR EYES WHEN WORKING NEAR THE BATTERY TO PROTECT AGAINST POSSIBLE SPLASHING OF THE ACID SOLUTION. IN CASE OF ACID CONTACT WITH SKIN OR EYES, FLUSH IMMEDIATELY WITH WATER FOR A MINIMUM OF 15 MINUTES AND GET PROMPT MEDICAL ATTENTION. IF ACID IS SWALLOWED, CALL A PHYSICIAN IMMEDIATELY.

 WARNING: BATTERIES NORMALLY PRODUCE EXPLOSIVE GASES WHICH CAN CAUSE PERSONAL INJURY. THEREFORE, DO NOT ALLOW FLAMES, SPARKS OR LIGHTED SUBSTANCES TO COME NEAR THE BATTERY. WHEN CHARGING OR WORKING NEAR A BATTERY, ALWAYS SHIELD YOUR FACE AND PROTECT YOUR EYES. ALWAYS PROVIDE VENTILATION.

 WARNING: WHEN LIFTING A PLASTIC-CASED BATTERY, EXCESSIVE PRESSURE ON THE END WALLS COULD CAUSE ACID TO SPEW THROUGH THE VENT CAPS, RESULTING IN PERSONAL INJURY, DAMAGE TO THE VEHICLE OR BATTERY. LIFT WITH A BATTERY CARRIER OR WITH YOUR HANDS ON OPPOSITE CORNERS.

1. Verify the vehicle owner's original concern by operating the engine (6007) to duplicate the concern.

2. Inspect to determine if one of the following mechanical or electrical concerns apply.

   
   
   

   VISUAL INSPECTION CHART

   Mechanical	Electrical
   Before attempting to test a battery, it is important to give it a thorough examination to determine if it has been damaged.	Batteries are tested to determine the state of charge and ability to crank an engine. The result of these tests is to show that the battery is either good, needs recharging, or must be replaced.
   Preliminary checks to the charging system should be made regardless of the fault condition. These checks include: Check the fuses/fuse links to the generator to ensure that they are not burned or damaged. This condition, resulting in an open circuit or high resistance, can cause erratic or intermittent charging system concerns. Check battery posts and cable terminals for clean and tight connections. Clean the posts and the cables to ensure good electrical contact. Check for secure connections at the generator output, voltage regulatorand engine ground. Also check the connection at the power distribution point. Check the generator drive belt to ensure proper tension and no slip between the generator pulley and the drive belt. Refer to Section 03-05. Check battery for full charge as outlined.	Before performing charging system tests on the vehicle, note conditions such as: slow cranking, discharged battery, charge indicator lamp stays ON with engine running, charge indicator lamp does not illuminate with ignition switch in RUN and engine not running, etc. This information will aid in isolating the part of the system causing the symptom. When a relatively new battery is discharged, test for current drain. The following are some of the most common current drain concerns: Glove compartment lamp stays on with the door closed. Engine compartment lamp stays on constantly. License plate lamp or interior lamp stays on constantly. Other electronic component malfunctions.

   
   

3. If the inspection reveals obvious concern(s) that can be readily identified, service as required.

4. If the concern(s) remains after the inspection determine the symptom(s) and go to the symptom chart.

1. All voltage measurements are referenced to the negative (-) battery post unless otherwise specified.

2. Do not make jumper connections except as directed. Improper connections may damage the voltage regulator or fuses/fuse links.

3. All key on measurements are made with the engine not running unless directed to start engine.
